Abstract

disposição de eixo de cames. a presente invenção refere-se a uma disposição de eixo de cames (1) para a alteração da posição do ângulo relativa de, pelo menos, um primeiro cames de um eixo de cames (2) em relação a um segundo cames do eixo de cames (2), sendo que, a disposição abrange um dispositivo de ajuste do ângulo (3), que apresenta um estator (40 e um rotor (5) disposto, podendo girar, em relação ao estator, sendo que, o rotor (5) está ligado com um eixo (6) à prova de rotação, sendo que, o estator (4) está ligado com um eixo oco (7) à prova de rotação, sendo que, o eixo (6) e o eixo oco (7) estão dispostos concêntricos um ao outro, senmdo que, o, pelo menos um, primeiro cames está ligado com o eixo (6) à prova de rotação, sendo que, o pelo menos um, segundo cames está ligado com o eixo oco (7) à prova de rotação e, sendo que, a ligação à prova de rotação entre o rotor (5) e o eixo (6) é produzida através de, pelo menos, um parafuso (8). a fim de estabelecer uma ligação firme entre o rotor e o eixo, que ocupa pouco espaço, a invenção provê que, o eixo (6) esteja encostado, com um lado frontal (9), na superfície de encosto (10) do rotor (5) e, por meio de, um parafuso (8) seja apertado contra a superfície de encosto (10), sendo que, o eixo (6), ao longo de sua extensão axial, que se encontra na área do rotor (5), apresenta uma superfície da seção transversal (a~ 1~) que se amplia até o lado frontal (9) para um valor maior (a~ 2~).camshaft arrangement. The present invention relates to a camshaft arrangement (1) for changing the relative angle position of at least one first camshaft cam (2) relative to a second camshaft cams (2), the arrangement comprising an angle adjusting device (3) having a stator (40 and a rotor (5) arranged which can rotate with respect to the stator and the rotor (5) is connected with a rotation-proof shaft (6), the stator (4) is connected with a rotation-proof hollow shaft (7), with shaft (6) and hollow shaft (7) are arranged concentric with each other, provided that the at least one first cam is connected with the rotation-proof shaft (6), and the at least one second cam is connected with the hollow shaft (7) The rotation-proof connection between the rotor (5) and the shaft (6) is produced by at least one screw (8) in order to establish an alloy. Firmly between the rotor and the spindle, the invention provides that the spindle (6) is abutted with a front side (9) on the abutment surface (10) of the rotor (5) and therefore whereby a screw (8) is tightened against the abutment surface (10), and the shaft (6) along its axial extension in the area of the rotor (5) has a surface of the cross section (a ~ 1 ~) extending to the front side (9) to a larger value (a ~ 2 ~).
